Efficacy and Safety Study of FP MDPI Compared With FS MDPI in Adolescent and Adult Patients With Persistent Asthma

Study drug and placebo were supplied in Teva multidose dry powder inhaler (MDPI) devices and provided for participants to use at home. Participants performed spirometry at every visit. Each participant was given a diary at each visit for use until the next visit. Rescue medication (albuterol/salbutamol) was dispensed at each visit, if needed, as determined by the investigational center personnel.
